And we're frustrated to report that they've thrown another clue our way but this may be the biggest one yet!
In a new interview, family matriarch Kris Jenner revealed that she's "over the moon" for Khloè Kardashian 'coz she's finally in "such a great place" in her life and is V happy with her NBA star bae Tristan Thompson.
"We love Tristan so much, and she's so happy, and she's been through so much," Kris told ET.
"Just seeing her be able to do something so creative with [her denim line] Good American — that's her passion."
She adds: "On top of it, to be in such a great place in her personal life is amazing. She's really happy. She lives most of the time now in Cleveland, so that's interesting, because she's not around every day."
Her emphasis on Koko being "in such a great place in her personal life" has fans *convinced* that this was a confirmation of Koko's pregnancy!
She went on to speak about her other pregnant daughter, Kylie Jenner.
The interviewer, obvs digging for dirt, asked Kris how she thinks her 20-year-old daughter will deal with the "major life changes" ahead.
Her response was basically a flat out confession that Kylizzle is expecting!
"I think she is very strong," Kris continued.
"I think the strength that she has as a woman and as an entrepreneur, a businessperson, and everything that she's got going on - she's really equipped to handle whatever comes her way.
"I'm so proud of that kid. She's a good girl with a big heart."
Well, that interview was as good as a straight-up confession, if you ask us!
